PS: I trying to compile without use Flex Builder 4, just, using Ant tasks.

are you still using 4.0.0.13323 or did you upgrade to the latest stable nighlty builds 4.0.0.13875 from 29th of January? I wanted to upggrade from beta 2 to 13875 yesterday and have problems (it seems it doesnt work even if it is stable nightly build, please read more here

and here is discussion on http://forums.adobe.com/thread/552806?tstart=0

I’m still searching for latesta stable nightly build, which really works and it seems 4.0.0.13323 works for you, so I can try it as well.

In Flash Builder you should be able to go to Project > Properties > Flex Compiler and check “Use Flex 3 compatibility mode”.

Note that while using Flex 3 compatibility mode you will be limited to Flex 3 components and won’t be able to add any spark features or components including s:Application.

If you want to mix and match halo and spark components, but still have the halo components look like they used to in Flex 3 then you can change the theme.

Here is a link to more information on what compatibility mode does other than just changing the theme:
